What is the percent of sulphur in ammonium sulphate?
The formula of ammonium sulphate is (NH4)2SO4, showing that each formula mass contains one sulphur atom. The formula mass of ammonium sulphate is 132.13, and the gram atomic mass of sulphur is 32.06. Therefore, the percent by mass of sulphur in ammonium sulphate is 100(32.06/132.13) or 24.26, to the justified number of significant digits.
What is the relative formula mass of ethanol?
46.068g
A piece of iron weighing 85.65 g was burned in air The mass of the iron oxide produced was 118.37 g use the molar mass of iron to convert the mass of iron used to moles?
If 85.65g of iron forms 118.37g of the oxide, the mass of oxygen combined with this mass of iron is 32.72g. Calculate the number of moles of iron and oxygen which have combined (after all, the formula of a compound shows the ratio of the number of moles of each element combined). Do this by dividing the mass reacted by the Relative Atomic Mass of the element concerned. i.e. For Iron it is 85.65/55.8 and for Oxygen 32.72/16. This gives a mole ratio of Fe:O as 1.53:2.04 or 3:4 Therefore the formula is Fe3O4
What is copper sulfates relative formula mass?
The anhydrous copper sulfate (CuSO4) has a molar mass of 159,62.
What is the mass of one mole of iron sulphate?
In one mole of each element there is... Fe - 56g O - 16g S - 32g Th equation is Fe2(SO4)3 56g x 2 = 112g 32g x 3 = 96g 16g x 12 = 192g 112g + 96g + 192g = 400g 400g
What is the relative formula mass for MgCO3?
relative formula mass of MgCO3
What is the percent of sulphur in ammonium sulphate?
The formula of ammonium sulphate is (NH4)2SO4, showing that each formula mass contains one sulphur atom. The formula mass of ammonium sulphate is 132.13, and the gram atomic mass of sulphur is 32.06. Therefore, the percent by mass of sulphur in ammonium sulphate is 100(32.06/132.13) or 24.26, to the justified number of significant digits.
Why is iron sulphate a compound?
Iron sulphate is a compound because it contains more than one element (three in this instance) in fixed ratios by mass to one another. There are at least two kinds of iron sulphate, those of iron(II) and iron(III). These have the same mass ratio between sulfur and oxygen, but the ratios of these two elements to iron are different in these two compounds.
Why was it necessary to weigh the iron filings accurately though the mass of copper sulphate taken was only approximate?
it is because iron is solid and can easily sublimes in aqueous copper sulphate
What is the formula mass of ferric sulphate Fe2SO43?
The molar mass of Fe2(SO4)3 is 399,88 g (anhydrous).
What is the formula mass of hydrogen?
The relative formula mass of a molecule of hydrgoen is two (2 x 1).
What is the relative formula mass of ethanol?
46.068g
What is the relative formula mass of each of the following compounds of potassium dichromate?
The chemical formula of potassium dichromate is K2Cr2O7; and the molecular mass is 294,185.
What is the relative formula mass of nitrate?
The chemical formula is (NO3)-; the mass is 62 g.
When a mixture of iron and sulfur is heated a compound called iron sulfide is madein an experiment 2.8g of iron made 4.4g of iron sulfide What mass of sulfur reacted with the 2.8g of iron?
3.2g ..... assuming it is iron (II) Sulphide FeS2. The relative atomic mass of iron is 56, sulphur is 32, so the ratio of masses of these two elements IN THE FORMULA = 56 : 64. If 2.8g of iron was used then, from the ratio, this will react with 3.2g of sulphur.
