Answer: 105.96
Explanation:
Sodium bicarbonate (Na2CO3)
Atomic mass of Sodium (Na) = 22.99
Atomic mass of Carbon (C) = 12.01
Atomic mass of oxygen = 15.99
Na2CO3 has a molar mass of (22.99x2) + 12.01 + (15.99x3) which is equal to
45.98 + 12.01 + 47.97 = 105.96
Thus, the molar mass of sodium bicarbonate is 105.96g/mol
The answer is C because salt water is hypertonic as compared to the solution inside the Amoeba cell. When it is placed in salt water it will lose water by exosmosis and will shrink.
