STatiana [176]3 years ago
7 0

The mass of the marble is greater than that of the water. The marble weighs more than an equivalent volume of the water. The force from dropping the marble breaks the surface tension of the water. The marble has greater mass and volume than the water.

A compound is 40% carbon, 6.7% hydrogen, and 53.3% oxygen. What is the empirical formula? (4 points)
Elis [28]

Answer:

CH2O

Explanation:

Dividing by the atomic masses:

40 / 12 = 3.333

6.7 / 1 = 6.7

53.3 / 16 = 3.331

The ratios are

3.333/ 3.333 : 6.7 / 3.333 : 3.331/3.333

= 1:2:1.

So it is CH2O.

Suppose you determined the density of a cube to be 1.40 g/cm3. would the density of the cube be different if you had a cube made
ki77a [65]
Density is mass/volume so if you double the mass you would also double the volume which means density would stay the same. Density is the amount of of matter in a given area and it is constant for the substance regardless of differences in mass or volume.
