Relative atomic mass of NaCl=23+35.5=58.5
2000kg / 58.5 = mass per relative atomic mass = 34.188
34.188 * atomic mass of Na, 34.188 * 23 = 786.325... = 790 kg (2s.f.)
Answer:
0.375 mols
Explanation:
- Relative atomic mass Ar of C=12×1=12
- Relative atomic mass Ar of O=16×2=32
- Realitive formula mass Mr is 12+32=44
mol:mass
1 : 44
x :16.5
cross multiply and get the answer
