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?

Respuesta :

1.587 ounces of sodium chloride

Answer:

Ounces of sodium required = 1.6 oz

Explanation:

Given:

Mass of sodium = 45 g

To determine:

Mass of the given amount of Na in units of 'ounces' (oz)

Calculation:

Unit conversion:

1 g = 0.03527 oz

The given mass in oz is:

[tex]= \frac{45\ g* 0.03528\ oz}{1\ g} =1.587 oz[/tex]

Rounding to 2 significant figures gives mass of Na = 1.6 oz
