How many moles of magnesium, Mg, are there in 4.75 grams of magnesium?

Nina [5.8K]

Molar mass Mg = 24.3 g/mol

1 mole mg ------------ 24.3 g
?? moles mg --------- 4.75 g

4.75 x 1 / 24.3 => 0.195 moles of Mg

hope this helps!

The empirical formula of a group of compounds is CHCl. Lindane, a powerful insecticide, is a member of this group. The molar mas

Sergeeva-Olga [200]

Answer:

Explanation:

since, n = molar mass / empirical formula mass

Empirical formula mass = Total mass of atoms present in empirical formula

CHCl = 12+1+35.5

= 48.5

Given, Molar mass = 290.8 g.

So, n = 290.8/48.5

= 5.995 , that is approx 6.

So, Molecular formula = n × Empirical formula

= 6 × CHCl

= $C_{6}H_{6}Cl_{6}$

So, Number of C = 6
