Answer:
About 1.99 g/mL
Explanation:
The density of a substance can be found using the following formula:
d= m/v
where m is the mass and v is the volume.
The mass of this substance is 49.1 grams and the volume is 24.7 milliliters.
m= 49.1 g
v= 24.7 mL
Substitute these values into the formula.
d= 49.1 g / 24.7 mL
Divide 49.1 g by 24.7 mL
d= 1.98785425 g/mL
We are asked to round to two decimal places, or the hundredth place. The 8 in the thousandth place tells us to round the 8 to a 9 in the hundredth place.
d ≈ 1.99 g/mL
The density of the this substance is approximately 1.99 grams per milliliter.
