Answer:
I solved the questions then counted how many significant figures in each answer
eg,
0.042m+1.33m =1.372m
1.372 has 4 significant figures
that's how you do others
Explanation:
6. 1.372m = 4 significant figures
7. 4.345g = 4 significant figures
8. 12L = 2 significant figures
9. 27.3cm = 3 significant figures
10. 0.975 = 3 significant figures
3.51 L
A. 1.50
9.01 x 1023 molecules* 1 mol/ 6.022×1023 molecules= 1.49618067087 moles
Rounded would be 1.50
Gravity is the answer.
490
98 for 1 mole, Hence for 5 moles 5 X 98 =490.
