Question

As a laboratory assistant, you measure chemicals using the metric system. For your current research, you need to measure out 45 grams of sodium chloride. The bottle you are using lists the amount in ounces. About how many ounces of sodium chloride will you need?

Answer 1

there are about 28 grams in an ounce so 45/28 is about 1.5

Answer 2

Answer: There is 1.587 ounces of sodium chloride that he will need.

Explanation:

Since we have given that

Quantity of sodium chloride in grams = 45 grams

We need to find the number of ounces of sodium chloride.

As we know that

1 ounce = 28.35 gram

So, 1 gram =
`(1)/(28.35)\ ounce`

So, 45 grams =
`(45)/(28.35)=1.587\ ounces`

Hence, there is 1.587 ounces of sodium chloride that he will need.
