Vectors include magnitude & direction so the third option is the correct answer :)
A. They are the same
<h3>Further explanation</h3>
Given
C3H6 and C4H8
Required
The percent compositions
Solution
%C = 3.12/42 x 100% = 85.71%
%H = 6.1/42 x 1005 = 14.29%
C₄H₈(MW=56 g/mol)
%C = 4.12/56 x 100% = 85.71%
%H = 8.1/56 x 100%=14.29%
So they are the same, because mol ratio of C and H in both compounds is the same, 1: 2
If your talking about mole. p
1 mole of water weighs 18 g
Therefore 0.5 mole of water weighs 9 g
According to Avagadro,
1 mol = 6.023 **10^23
atoms
So,
0.5 mol = 3.0115 **10^23
molecules of water
Each water molecule contains 2 hydrogen atoms .
Therefore
2** 3.00115**10^23
atoms of hydrogen are present in 9g of water
Answer:
The answer is
6.02⋅1023
Answer:
Iodine is a mineral found in some foods. The body must have iodine to make thyroid hormones. The hormones control the body's metabolism and many other important functions. Without iodine, thyroid hormone production can decrease.
