A grain of sand has a mass of [tex]2.6 \times 10^{-3}[/tex] grams. A grain of salt has a mass of [tex]6.5 \times 10^{-2}[/tex] grams. How many times greater is the mass of the grain of salt than the mass of the grain of sand?

Answer :

Let
x-----------> mass a grain of salt
y-----------> mass a grain of sand
r----------> ratio mass a grain of salt than mass a grain of sand

we know that
x=6.5 × 10–2 gram
y=2.6 × 10–3 gram
r=x/y----------> r=[6.5 × 10–2]/[2.6 × 10–3]----------> r=25

the answer is
the mass of the grain of salt is 25 times greater than the mass of the grain of sand
