The normality of 4 percent(wt./vol.) of NaOH is?
one liter of water weighs 1000g 4percent of 1000g is 4*1000/100=40g of NaOH molar mass of NaOH = 23+16+1=40g so this solution contains 1 mole /Liter the correct answer is a)
How much is 1 MB in pixels or percent?
I have no idea how you are trying to compare MB with percent. Unless you mean what percent of your storage it occupies? Depends on how much storage you have... if you have 128 MB storage, 1 MB occupies 1/128 = 0.78%. Now, by pixel depends on the image format. Most likely you are using JPEG format images, which are compressed, and it will vary greatly. On the average, though, I would expect 1 MB to be around 3 megapixels (3,000,000 pixels). If you are using Windows BMP images, with 24-bit colour, then 1 MB = 349,525 pixels (0.35 megapixels). As you can see, JPEG compression is far more efficient than uncompressed BMP format.
How do you handle your game volume when streaming on Twitch?
In game volume controls.You’ll want to make sure the game volume is at a comfortable level for you, but not too loud on stream.OBS gain controlThis is the sliding meter in the audio window. A standard setting would be anything between 0.0 and -6.0OBS Audio FX settingsOBS has a full suite of audio FX tools, including noise gating (preventing tiny sounds from being picked up,) noise reduction, compression, gain and more.PC Volume ConrolIf after all of that you find that the game is too loud in your ear when it’s right on your stream, or vice versa, turn to Windows or your PC’s normal audio control options. Get the audio level correct in OBS first, then adjust to your preference in your headphones.For your audio meters in OBS, those colors on the bar are important. If it doesn’t hit yellow, the sound will likely be too quite or your viewers will be raising their volume significantly to hear it. If it’s entering the red, it’s doing what I call “pushing” and will cause the speakers to put out crushed, really unpleasant sound that’s way too loud.
Calculate the volume of air at 30 degress C and 1.00 atm that is needed to burn completely 10.0 g of propane ?
Moles C3H8 = 10.0 g / 44.097 g/mol= 0.227 C3H8 + 5O2 >> 3 CO2 + 4 H2O moles O2 needed = 3 x 0.227= 0.681 V (O2) = nRT / p = 0.681 x 0.0821 x 303 K / 1.00 atm = 16.9 L volume air = 16.9 x 100 / 21.0 = 80.7 L
What is molarity, molality, percent by mass, mole fraction, mole percent?
1) Molarity is the number of moles divided by volume of solvent in liters. 28.0 g C₆H₁₂O₆ (1 mol C₆H₁₂O₆ / 180 g C₆H₁₂O₆) = 0.156 mol C₆H₁₂O₆ 0.156 mol C₆H₁₂O₆ / 0.384 L = 0.405 M C₆H₁₂O₆ 2) Molality is the number of moles divided by mass of solvent in kilograms. 0.156 mol C₆H₁₂O₆ / 0.350 kg = 0.444 m C₆H₁₂O₆ 3) Percent by mass, as the name implies, is the mass of solute divided by total mass times 100%. 28 g C₆H₁₂O₆ / (350 g + 28 g) * 100% = 7.41% C₆H₁₂O₆ by mass 4) Mole fraction is the number of moles of solute divided by total moles. 350 g H₂O (1 mol H₂O / 18 g H₂O) = 19.444 mol H₂O 0.156 mol C₆H₁₂O₆ / (19.444 + 0.156) = 0.008 mol fraction C₆H₁₂O₆ 5) Mole percent is mole fraction times 100%. 0.008 * 100% = 0.8% C₆H₁₂O₆ by moles
I couldn't shrink the volume of C drive beyond 5 GB even though I have 30 GB unused memory (73 GB total). What should I do?
Thanks for the A2A. I will not go into much detail. The amount you can shrink is determined solely by a percentage, which means that the more stuff you put in C Drive after your OS installation, the lesser you can shrink it. So, the trick would be to re-install your OS (and thereby re-format your C drive) followed by shrinking it. That should give you the maximum.Then again, if you want to assign a specific amount of space, the most reliable way would be to format the entire hard drive and partition accordingly.Cheers!
