Answer:
8000 metres is equal to 4.971 miles
equation
8000 (number of meters) divided by 1609.34 ( equivalent of miles in one meter)
is equal to 4.971
Popcorn and salt as the mixtures are substances which are formed by mixing other substances
Answer:
C
Explanation:
1. The molecule has to have a ratio of 1 hydrogen to 1 oxygen.
2. Hydrogen = 1amu, Oxygen = 16amu. (2*2)+(16*2) = 34amu
From mole ratios, the mass ratio of different elements can be predicted. Also the volume can be predicted based on density for liquids and ideal gas law equation for gases. From the mole ratios, the empirical formula can be predicted, as well as the molecular formula given another data which is mass of the sample.
