I don't know what the problem is, but here are some rues to help you out:
- All non-zero figures are significant
- When a zero falls between non-zero digits, that zero is significant.
- When a zero falls after a decimal point, that zero is significant.
- When multiplying and dividing significant figures, the answer is limited to the number of sig figs equal to the least number of sig figs in the problem.
- When adding and subtracting, the answer is limited to the number of decimal places in the number with the least number of decimal places.
Answer:
homogenous is a uniform and consistent mixture ; heterogenous is a mixture that is non-uniform
Explanation:
usually if you can separate the mixture/particles it is heterogenous. For example, pizza is heterogenous because you can separate the dough from the tomato sauce from the cheese. vinegar is homogenous (cannot separate mixture)
Fe: 2 x 55.845 = 111.69
O: 3 x 15.9994= 47.9982
111.69 + 47.9982 = 159.69 g/mol
