Answer:
0.03g
Explanation:
Given parameters:
Number of moles of Na = 0.00125mole
Unknown:
Mass in grams of Na = ?
Solution:
To find the mass of this substance, we simply multiply the number of moles with the given molar mass of Na.
Mass of Na = number of moles x molar mass
Mass of Na = 0.00125 x 23 = 0.03g
the formula for density is p=m/v
m aka the mass = 5.4; the v aka the volume = 8
so, p=5.4/8
p= 0.675 g/cm^3
*let's just say the mass' unit is gram so the unit for the density is g/cm^3
