if the average salinity is 35 parts per thousand how many grams of dissolved salts will 500g of seawater contain
1) B
2) D
3) D
4) B
5) C
6) B
7) A
8) B
I need that broken down cause I'm 11 and I have no idea what I am doing. Help!

3.5 percent
35 parts/1000 parts = 35g/1000g so how many grams NaCl would be in 1/2 that amount? Wouldn't that be just 35 x (500/1000) = ?
Look at it another way.
35g/1000g = 0.035g/g. So if there are 0.035g in 1g sea water there would be 0.035 x 500 = ? in 500 g sea water.
