What is 120g of chlorine gas converted into mol?
Remember moles = nass(g) / Mr ( Relative Moleculr Mass) . mass = 120 g Mr =35.5 x 2 = 71 ( Because chlorine exists as a diatomic gas Cl2). Hence moles(Cl2) = 120 /71 = 1.690
How many grams of fluorine are needed to react with 6.20 g of phosphorus?
Find number of moles of phosphorusmolar mass of phosphorus is 30.97g/moldivide mass by molar mass to get the moles of phosphorus please that your molar mass mast be multiplied by 4 because you have four phosphorus atoms. 30.97*4= 123.88 g/moln= m/M = 62.0g/123.88g/mol= 0.50 molesTheoretically, there are 6 times the number of moles in fluorine than there are in phosphorus because of the ratio 1:6 but fluorine is diatomic gas so we multiply the number of moles by 12 instead of 6. 6 from the ratio times from fluorine being diatomic gas.So 0.5*12=6 moles of fluorine. we multiply that by the molar mass of fluorine multiplied by 12 because we 12fluorine atoms.So, 6= m/228g/mol so to find mass of fluorine we multiply moles times molar mass it gives us 1368g.
How many moles of SO2 are present in 250.0 g?
Number of moles is determined by dividing molar mass into the number of grams. SO2 has a molar mass of 64.066 g. To find the number of moles in 250.0 g of SO2, divide 250.0 g by 64.066 g. This gives you just over 3.9 moles.
How many moles are in 223.2 g of iron?
The number of moles is 4.
How many moles are in 6.80 g of Al2O3?
Number of moles = weight (in g) / molecular weight = 6.80 / 101.961 = 0.0667 moles or 66.7 milli moles.
How many moles of phosphorus atoms are in a 100 g sample of phosphorus?
The gram atomic mass of phosphorus is 30.9738, and by definition, a mole of such atoms contains Avogadro's Number of atoms. Therefore, 100 g of phosphorus contains 100/30.9738 or 3.23 moles, to the justified number of significant digits.
How many grams of phosphorus trichloride are present in 3.42 moles of this compound?
3,42 moles of phosphorus trichloride have 469,6686 g.
How many grams of phosphorus are present in 4.70 moles of tetraphosphorus decaoxide?
4,70 moles of tetraphosphorus decaoxide contain 582,56 g phosphorus.
How many moles of calcium represent in 120 grams?
120 g calcium is equal to 3 moles.
How many atoms of phosphorus are in a 0.577 g sample?
1.12 x 10^22 atoms PFirst determine the number of moles in the 0.577 g sample of phosphorus, determine the number of moles in the sample. Then multiply the moles by 6.022x10^23 atoms/mol.0.577 g P x (1 mol P/30.974 g P) x (6.022x10^23 atoms P/1 mol P) = 1.12 x 10^22 atoms P
