(c) copper(I) sulfate

(d) hydrobromic acid

Step-by-Step Solution:
Step 1 of 3

Solution 98P

Here, we are going to calculate the formula mass.

Formula mass is the average mass of the molecule of a compound.

Formula mass of a molecule can be calculated by using the following formula.

Formula mass = (no of atoms of the element ) x (atomic mass of 1st element) + (no of atoms of the element ) x (atomic mass of 2nd  element) +...

(a) barium bromide

The chemical formula of the compound is BaBr2.

Formula mass

=  1 x(atomic mass of Ba)+ 2 x(atomic mass of Br )

= 1 x 137.327 amu + 2 x 79.904 amu

= 137.327 + 159.808 amu

= 297.135 amu

The formula mass of  barium bromide is 297.135 amu.

(b) dinitrogen trioxide

The chemical formula of the compound is N2O3.

Formula mass

=  2 x(atomic mass of N)+3 x(atomic mass of O )

= 2 x 14.00 amu + 3 x 16.00 amu

= 28.00 + 48.00 amu

= 76.0 amu

The formula mass of  dinitrogen trioxide is 76.0 amu.

(c) copper(I) sulfate

The chemical formula of the compound is Cu2SO4.

Formula mass

=  2 x(atomic mass of Cu)+1 x(atomic mass of S ) + 4x (atomic mass of O )

= 2 x 63.54 amu + 1 x 32.065 amu +4 x 16 amu

= 127.08 amu + 32.065 + 64 amu

= 223.145 amu

The formula mass of  copper(I) sulfate is 223.145 amu.

(d) hydrobromic acid

The chemical formula of the compound is HBr.

Formula mass

=  1 x(atomic mass of H) +1 x(atomic mass of Br )

= 1 x 1.008 amu + 1 x 79.904 amu

= 80.91 amu

The formula mass of  hydrobromic acid  is 80.91 amu.
