Answer:

d=1.5\ g/cm^3

Explanation:

Given that,

The mass of the rock, m = 15 g

The volume of the rock, V = 10 cm³

We need to find the density of the rock. The density of an object is equal to the mass per unit volume such that,

d=\dfrac{m}{V}\\\\d=\dfrac{15\ g}{10\ cm^3}\\\\d=1.5\ g/cm^3

So, the density of the rock is equal to 1.5\ g/cm^3.

Answer:

C.) They have fewer electrons than protons

Explanation:

Charges on ions are determined by the ratio of electrons to protons. Neutral elements have the same number of protons and electrons. Remember: protons have a positive charge and electrons have a negative charge. However, based on the amount of electrons these elements have, some are more or less willing to give up their electrons to participate in ionic bonding. Potassium usually gives up 1 electron because this satisfies the octet rule. By removing this electron, the element has more protons than electrons, giving it an overall +1 charge.

Calculate the formula mass for the compound tin(IV) sulfate.
stellarik [79]
The molecular formula for tin(IV)  sulfate is Sn(SO₄)₂.
mass of sulfur S = 32.065
as there is 2 sulfur in tin (IV) sulfate = 32.065 x 2 = 64.13
mass of oxygen = 15.999 and there are 8 oxygen atoms in the formula; 
8 x 15.999 = 127.992
mass of tin = 118.71
now add all the masses = 64.13 + 127.992 + 118.71 = 310.832 
formula mass of tin(IV) sulfate is 310.832
