Jim wants to react hydrogen and oxygen to get 36 grams of water. If he starts with 4 grams of Hydrogen (H), then how many grams
serious [3.7K]

Answer:

Mass of Oxygen = 32 grams

Explanation:

Given:

Mass of water = 36 grams

Mass of Hydrogen = 4 grams

Find:

Mass of Oxygen

Computation:

Using Law of Conservation of mass

Mass of water = Mass of Hydrogen + Mass of Oxygen

36 grams = 4 grams + Mass of Oxygen

Mass of Oxygen = 32 grams

Consider 70.0-g samples of two different compounds consisting of only sulfur and oxygen. One of the compounds consists of 35.0 g
Mariana [72]

Answer:

1 : 1.5

Explanation:

First Sample;

Ratio of sulfur and Oxygen

Mass of sulfur : Mass of oxygen

Mass of oxygen = Mass of sample - Mass of sulfur = 70 - 35 = 35g

35g : 35g

1 : 1

Second Sample;

Ratio of sulfur and Oxygen

Mass of sulfur : Mass of oxygen

Mass of oxygen = Mass of sample - Mass of sulfur = 70 - 28 = 42g

28g : 42g

1 : 1.5

Further reducing it to make oxygen 1;

0.6667 : 1

ratio in whole numbers of the masses of sulfur that combine with 1.00 g of oxygen between the two compounds;

0.6667 : 1

1 : 1.5
