Answer:
35g/l
Explanation:
Salinity is practically the saltiness of the water, in basic terms. It's basically the amount of salt dissolved in water. Ocean water has a salinity of around 35g/l (that's about 3.5% of which is dissolved salt in water!). However, Atlantic Ocean (the ocean with the saltiest water), can range up to 37g/l.

1.9 mol H2.
3.8 mol HCl * (1 mol H2 / 2 mol HCl) = 1.9 mol H2
The scientific notation of 420,000 is : 4.2 x 10 ^ 5
Answer:
behaviors that are passed down genetically
Assuming the temperature is 20° C,
100 g of water dissolves 34 g,
200 g of water will dissolve: 200 x 34 / 100
= 68 g
The third option is correct.
