Answer:

Protons contribute to the mass of an atom and provide the positive charge to the nucleus. The number of protons also determines the identity of the element. ... Since the atom is electrically neutral, the number of electrons must equal the number of protons.

Which of the following is the largest volume?

Artist 52 [7]

I will use this conversion:

1m = 1000 mm => 1 = 1m / 1000mm

1 m = 100 cm=> 1 = 1m / 100cm

1m = 10 dm=> 1 = 1m / 10 dm

So,

B) 3.8 * 10^7 cm^3 = 3.8 * 10^7 cm^3 * [1m / 100cm]^3 = 38 m^3

C) 3.8 * 10^5 dm^3 * [1m / 10 dm]^3 = 380 m^3

D) 3.8 * 10^8 mm^3 * [1m / 1000 mm]^3 = 0.38 m^3

Now you can compare the four volumes and conclude which is the largest.

Answer: option C) 3.8 * 10^5 dm^3

What is the percent composition of Sb2F3.What is the percent composition of F in this molecule? Round the answer to five signifi

poizon [28]

Answer:

$\%F=18.967\%$

Explanation:

Hello,

In this case, a percent composition is computed by considering the atomic mass of each element in the compound as well as the number of atoms and the molar mass of the compound. Thus, Sb2F3 has a molar mass of 300.52 g/mol, antimony has an atomic mass of 121.76 g/mol and fluorine 19.0 g/mol, therefore, the percent composition of fluorine which has three atoms with five significant figures is:

$\% F=\frac{3*19.0g/mol}{300.52g/mol}*100\%\\ \\\%F=18.967\%$

Best regards.
