Answer:
Molecular mass
Explanation:
Molecular formulas is the actual number of atoms of each element in the compound while empirical formulas is the simplest or reduced ratio of the elements in the compound.
Thus,
Molecular mass = n × Empirical mass
Where, n is any positive number from 1, 2, 3...
Thus if the molecular mass is known, then we can find the value of n which results to molecular formula.
We are asked to give two possible explanation when bubbles are formed as two colorless solutions are mixed together. Presence of bubbles means that there is a gas formed in the products side and that the one of the reactants can be an acid.
The density of the rectangular block in g/mL is 7.0.
<u>Given the following data:</u>
- Mass of block = 22.8 gra1.94 kg
- Length of block = 3.21 cm
- Height of block = 1.84 in.
To find the density of the block in g/mL:
First of all, we would determine the volume of the rectangular block by using the following formula:
× ×
<u>Conversion:</u>
1 in = 2.54 cm
5.83 in = X cm
Cross-multiplying, we have:
× ×
Volume = 277.16 cubic centimeters.
<u>Note</u>: Milliliter (mL) is the same as cubic centimeters.
1000 grams = 1 kg
Y grams = 1.94 kg
Cross-multiplying, we have:
Y = 1940 grams
Now, we can find the density:
<em>Density </em><em>= 7</em><em>.0 g/mL</em>
Therefore, the density of the rectangular block in g/mL is 7.0.

I believe that the answer to your question is false! I'm not 100% sure but I know a thing or 2 about science
Answer:
Material is less dense than water so it will float in water.
Explanation:
Given data:
Mass of material = 110 g
Volume of material = 312 cm³
Will it float or sink in water = ?
Solution:
First of all we will calculate the density of material.
d = m/v
d = 110 g/ 312 cm³
d = 0.35 g/cm³
The density of water is 1 g/cm³ it means material is less dense than water so it will float in water.
