70 points chemistry need it to be done asap if you know the answer

question 1
in a solution, there is 1 g of nacl for every 5 g of water.

what is the ratio of sodium to water?

a)1nacl : 6h2o, because the mass of the solution equals 1 g of nacl
b)1nacl : 5h2o, because in the solution, for every 1 g of nacl there are 5 g of h2o
c)6nacl : 1h2o, because the total mass of the solution will be 1 g of h2o
d)5nacl : 1h2o, because in the solution, for every 5 g of h2o there is 1 g of nacl

question 2
how many mol of potassium (k) are present in cereal that claims to have 7.00 g of potassium per serving?
2.7^4 × 10^2 g k
1.7^9 × 10^–1 g k
3.1^3 × 10^–1 g k
1.5^7 × 10^1 g k

question 3
how many particles are in 1.40 x 107 mol of aluminum (al)?

(hint: remember that there are 6.02 x 1023 particles in a mol of an element.)

2.3^3 × 10^–17 particles al
8.4^3 × 10^30 particles al
3.7^8 × 10^8 particles al
6.2^5 × 10%5 particles al
