Answer:
<u>Explanation</u>:
<u>Number of molecules for </u>
Atomic mass of Na + H + C + 3(O) = 22.99 + 1.008 + 12.01 + 3 × 16.00 = 84.00 g/mol
<u>Number of molecules for for </u>
= Atomic mass of 3(Na) + P + 4(O)
= 3(22.99) + 30.97 + 4(16.00) = 163.94 g/mol
When light travels from air into water,it slows down,causing it to change directions slightly
