Agrain of sand has a mass of 2.6 × 10–3 gram. a grain of salt has a mass of 6.5 × 10–2 gram. how many times greater is the mass of the grain of salt than the mass of the grain of sand?

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
