How do you convert grams to moles using avogadros number?
You don't need to use Avogadro's number, you need the mass of the molecule in atomic units. Mass / molecular mass = moles eg for water, 36 grams / 18 atomic units = 2 moles
How many moles are in 45g of F?
The molecular mass of fluorine gas, F2 is 2(19.0) = 38.0Amount of F2 = mass of sample/molar mass = 9.5/38.0 = 0.25mol There are 0.25 moles of fluorine in a 9.5g pure sample.
How do you convert grams to molecular mass?
Suppose you have 1g of H2O and you want to convert that to moles. You multiply 1g by the inverse of molar mass to get the moles of H2O: 1g H2O *(1mol H2O/18g H2O)= 0.56 moles of H2O in 1g of H2O. You get 18g = 2(1.008)+1(16.00).
How many moles of water are on 72.08g of H2O?
The molecular formula of water is H2O. The atomic mass of H2O is 2(1.0) + 16.0 = 18.0Amount of H2O = mass of pure sample/molar mass = 75/18.0 = 4.17mol There are 4.17 moles of water in a 75 gram pure sample.
3 L of a gas weighs 2 g What is the molecular mass?
3 L / 22.414 /mole = 0.1338 moles of the gas 2 g is 0.1338 moles, or 2/0.1338 = 14.948 g/mole is the molecular weight. ( no real gas this light...methane is closest at 16 g/mole)
How many grams are in 2.5 moles of sulfuric acid?
The mol mass of sulfuric acid is 98.078 g/mol, 98 g of sulfuric acid therefore contains 0.9992 moles. Using consistent significant figures and your calculations, 98 g sulfuric acid would be equal to 1.0 mol sulfuric acid.
Millimoles to grams?
number of moles present = molar mass (g) 1 mol The molar mass is the sum of the atomic masses present in a compound. Be sure to take quantity into acount. For intance... the molar mass of H2O is 18.02 because 1.01+1.01+16=18.02
How many moles of aluminum are present in 856g of aluminum sample?
Moles = Mass/ Relative Molecular Mass Aluminum forms Al2 compounds, so the relative molecular mass is 2 * 13 = 26. 856/26 = 32.9 (3sf)
What is the mass of 1.5E-2 moles of xenon tetra- fluoride?
mass (in grams) = number of moles x molecular weight. So for 0.015 moles of XeF4, the mass = 0.015 x 207.284 = 3.11 g
What will be the mass of 2.05 1016 molecules of H2SO4.?
molar mass of H2SO4= 2(1)+ 32 + 4(16)=98g/molno. of moles = no. of molecules/6.02*10^23no. of moles = 2.05*10^16/6.02*10^23no. of moles = 3.406*10^(-8)molmass of a substance = molar mass*no. of moles= 98*3.406*10^(-8)=3.34*10^-6g Ans
What is the mass in grams of three moles of H2SO4?
H2SO4 H= 1X2 = 2 S=32X1=32 O=16X4=64 TOTAL: 98 98x3= 294 GRAMS =))
How many gmole of chromium II hydroxide?
So you have 2 moles of Chromium (Cr). Use equation moles=mass (in grams)/RMM. The bottom can be called Relative Molecular Mass (RMM), or Relative Atomic Mass (RAM) depending on the situation. Chances are you know it as Molar mass. You can call it that too. Using moles= mass (g)/RMM --> 2 moles = mass (g)/51.996 --> 2 x 51.996 = the mass in grams of Chromium --> 103.992g in 2 moles of Chromium.
How do you calculate 1m h2so4?
Use the equation Moles(m) = mass(g) / Mr (Relative Molecular Mass). To calculate the Mr , refer to the Periodic Table, for Atomic Masses. For H2SO4 We have H x 2 = 1 x 2 = 2 ( 1 is the atomic mass of H ) S x 1 = 32 x 1 = 32 ( 32 is the atomic mass of S). O x 4 = 16 x 4 = 64 (16 is the atomic mass of O). Adding 2 + 32 + 64 = 98 the Mr of H2SO4 Substituting into the eq'n above 1 mole = mass(g) / 98 Algebraic rearrangement mass(g) = 1 mole X 98(Mr) mass(g) = 98 grams. is the mass of 1 mole of H2SO4 .
What is the mass of 11 moles of KCl?
The atomic mass of potassium is 39 The atomic mass of chlorine is 35.5 The formula mass of KCl is the sumof these. This is the mass in grams of one mole of KCl. Use this as a conversion factor to find mass of 11 moles
How many grams does 3 moles of CO2 weigh?
Atomic mass of C = 14g/mol Atomic mass of O = 16g/mol Molecular mass of CO2 = 12 + 2(16) = 44g/mol mass = number of moles x molecular mass mass = 3 mol x 44g/mol = 132g
What mass of calcium phosphate can be completely reacted with 1.523 moles of sulfuric acid?
Balanced equation first. Ca3(PO4)2 + 3H2SO4 -> 3CaSO4 +2H3PO4 1.523 moles H2SO4 (1 mole Ca3(PO4)2/3 moles H2SO4)(310.18 grams/1 mole Ca3(PO4)2) = 157.5 grams of Calcium phosphate
How do you convert grams to moles using avogadros number?
You don't need to use Avogadro's number, you need the mass of the molecule in atomic units. Mass / molecular mass = moles eg for water, 36 grams / 18 atomic units = 2 moles
