according to the law of conservation of mass, if an atom of element a has a mass of 2 units, while an atom of element b has a mass of 5 units, what would be the mass of the compound a3b2? a 16 units b 7 units c 11 units d 19 units
Answer
Explanation:
Step1: Calculate mass of A in compound
The compound is (A_3B_2). Each atom of A has a mass of 2 units and there are 3 atoms of A. So mass of A in the compound is (3\times2 = 6) units.
Step2: Calculate mass of B in compound
Each atom of B has a mass of 5 units and there are 2 atoms of B. So mass of B in the compound is (2\times5=10) units.
Step3: Calculate total mass of compound
Total mass of compound (A_3B_2) is mass of A + mass of B, which is (6 + 10=16) units.
Answer:
a. 16 units
