Answer 1

Answer:

55.59

Explanation:

In cuso4.5h2o ,molar mass=63+32+16×4+5×2×1+5×16=259amu

mass of oxygen=4×16+5×16=64+8o=144amu

%of oxygen=144÷259×1oo=55.59

Answer 2

${\blue{\huge{\text{Answer}}}}$

55.9%

${\red{\bold{\text{Explanation:-}}}}$

In CuSo4.5H2O

Molar mass=63+32+16×4+5×2×1+5×16=259 amu

Mass of oxygen=4×16+5×16=64+80=144 amu

%of oxygen=144÷259×100

=55.59%
