Find the density of a substance that’s had a volume of 24.7mL and a mass of 49.1g. Give the answer with two decimals.

1.99 g/mL

Explanation:

Use the formula d = m/v, where m is the mass and v is the volume.

Plug in the values:

d = 49.1/24.7

d = 1.99 g/mL

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.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

thats a little if u want the answer just look it up on google thats what i do haha : )
