The answer to your question is: i have to answer correct first number three and second number one.
Explanation:
1.-regulate cell processes
: Nucleic acids are located inside the nucleus and the nucleus is the brain of the cell, it says what functions must be done, then I think this option is correct.
2.- provide structure
: Nucleic acids are large molecules but very weak, the couldn't be able to give structure. This option is wrong.
3.- transmit genetic information
: The main function of nucleic acids is transmit genetic information, so this option is correct.
4.- fight disease: Nucleic acids are useful to transmit genetic information, and saying the functions a cell must do but fight against diseases is not one of their functions.

Answer:
Mg(NO4)2 is 180.3 g/mol
Explanation:
First find the substance formula.
Magnesium Nitrate.
Magnesium is a +2 charge.
Nitrate is a -1 charge.
So to balance the chemical formula,
We need 1 magnesium atom for every nitrate atom.
2(1) + 1(-2) = 0
So the substance formula is Mg(NO4)2.
Now find the molar mass of Mg(NO4)2.
Mg = 24.3 amu
N = 14.0 amu
O = 16.0 amu
They are three nitrogen and twelve oxygen atoms.
So you do this: 24.3 + 14.0(2) + 16.0(8) = 180.3 g/mol
So the molar is mass is 180.3 g/mol.
The final answer is Mg(NO4)2 is 180.3 g/mol
