To calculate the mass of a substance in grams, you need to multiply the number of moles by the molar mass of the substance. The molar mass of H2SO4 (sulfuric acid) is approximately 98.08 g/mol. Therefore, the mass of 6.25 moles of H2SO4 would be 6.25 moles x 98.08 g/mol = 613 grams.

What will be the pressure of a sample of 48.0 grams of oxygen gas in a glass container of volume 5.2 L at 25 degrees Celsius?
Molar Mass O2: 32.00, Molar Mass CO2: 44.01, T= 21C+273= 294Kelvins V=5.00 L Grams of O2=20.0 so moles O2= 20.0g/32.00g=.625g/mol Grams of CO2=4.4 so moles CO2= 4.4g/ 44.01=.1 Total moles: .625+.1= .725 mols (this is n) Ideal Gas Law: PV=nRT....Rearrange and solve for pressure. P=nRT/V.....R is the constant which is equal to .08206L*atm*mol P=(.725)(.08206)(294K)/(5.00L) P= 3.5atm
How do you get the density when the volume is bigger than the mass?
You can think of the answer to this from your real life experience;As you know, here on the ground (I'm assuming you're on the ground), anything with mass has weight. Even in outer space, things with more mass take more effort to move around.You know from experience that a block of metal is more dense than a block of dry wood of the same size, because it's heavier and harder to move around.So you already know: The density of something is how much mass is crammed into a certain size space (volume). You might say the density is the amount of mass per unit of volume; density = mass / volumeWith basic algebra, you then know that mass = density * volumeif you don't know basic algebra:(density) * volume = (mass / volume) * volumedensity * volume = mass * (volume / volume)density * volume = mass * 1density * volume = mass
What is the pH of 535 ml of gaseous HCL at 26.5 degree C and 747 mmHg is dissolved in enough water to prepare 625ml solution?
Let's try this. PV = nRT ( 26.5 C = 299.65 K )(535 ml = 0.535 Liters ) (747 mmHg)(0.535 Liters) = (n)(62.36 L*torr/mol*K)(299.65 K ) = 0.021387 moles HCl(g) now.... Molarity = moles solute/Liters of solution (625 ml = 0.625 Liters Molarity HCl(g) = 0.021387 moles/0.625 Liters = 3.422 X 10^-2 M -log(3.422 X 10^-2 M) = 1.4657 pH final answer ( trim to significant figures )
What pressure is exerted by 625 mole of a gas in a 45.4 L container at -24 C?
The equation to use is the Ideal Gas Law: PV = nRT Rearranging for the unknown in your question (P) gives: P = nRT/V n = Number of moles: 625 R = Gas constant: 0.0821 L·ATM·mol-1·K-1 T = Temperature in Kelvin = 249 (Which is temperature in Celsius +273). V = Volume 45.4L So P = (625 x 0.0821 x 249) / 45.4 = 281.4 Atmospheres.
How many grams are in 625 milligrams?
There are 0.625 grams in 625 milligrams. You can convert milligrams to grams by dividing the milligrams by 1000.
How may grams is in 625 mg?
1 milligram (mg) = .001 grams (g) = 1/1000 grams Therefore, 625 mg * 1/1000 grams = .625 g which is less than 1 gram (g).

A 0.25kg object displaces 625 ml of water round to nearest hundredth what is its specific gravity?
Specific gravity is the ratio of the mass of some volume of substance to the mass of same volume of water. Here 0.25 kg ie 2500 g is the mass of some volume of given substance. The volume of water displaced is 625 mL ie 625 cc. 1 cc of water has a mass 1g. So 625 mL has 625 g. Hence the specific gravity is 2500/625 = 4 (no unit)
