The formula of epsom salt is MgSO4. 7H2O
Mass of water crystal = 2.00-0.98 = 1.02 g
moles of water = 1.02/18 = 0.0566 moles
Moles of mgso4 = 0.98/(24.31+32.07+64) = 0.0081 moles
So ratio is 0.0566/0.0081= approx 7
So the formula of epsom salt is MgSO4. 7H2O
Mass is a physical body's total amount of matter. It also serves as a gauge for the body's inertia, or resistance to acceleration (change in velocity) in the presence of a net force. The strength of an object's gravitational pull to other bodies is also influenced by its mass.
The kilogram is the primary mass unit in the SI (kg). Even though weight is frequently measured using a spring scale rather than a balance scale and directly compared with known masses, mass is not the same as weight in physics. Due to the lower gravity on the Moon, an object would weigh less than it does on Earth while maintaining the same mass.
