Answer:
1.400 mol
Explanation:
To convert grams to moles, you will need the molar mass. The molar mass of iron(iii) sulfate is 399.88 g/mol. Divide grams by the molar mass to find moles.
(560.0 g)/(399.88 g/mol) = 1.400 mol
There are 1.400 mol present in 560.0 g of iron(iii) sulfate.
Answer:
One million of silver atoms weigh 1.79 xx 10^(-16)g. Calculate the atomic mass of silver. Atomic mass of silver =107.8g=107.8u
Answer: The density of kerosene is 
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of kerosene = mass of beaker with kerosene - mass of empty beaker = 60 g - 20 g = 40 g
Volume of kersone =
Putting in the values we get:
Thus the density of kerosene is
