Calculate the mass of a 0.253mL sample of a liquid with a density of 1.38 g/mL.

The answer is

Explanation:

The mass of a substance given the density and volume can be found by using the formula

From the question

volume of liquid = 0.253 mL

density = 1.38 g/mL

Substitute the values into the above formula and solve for the mass

We have

mass = 1.38 × 0.253 = 0.34914

We have the final answer as

Hope this helps you

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.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
