118? But there are some spots for elements that haven't been discover. right? <span />
Qualitative (physical e. g. colour) and quantitative (numerical e. g. 3 grams) data
Organic molecule. In particular, a carbohydrate.
Answer:
faster, and the ingredient will be a liquid.
Explanation:
Hello!
We have the following data:
m (mass) = 4.6 grams
MM (molar mass) of H2O
H = 2 * 1 = 2 amu
O = 1 * 16 = 16 amu
--------------------------
MM (molar mass) of H2O = 2 + 16 = 18 g/mol
Solving:
Establishing a relation with Avogadro's number (6.10²³) we have:
18 g of H2O --------------- 6.10²³ molecules
<span>4.6 g of H2O --------------- y molecules
