Answer:
1. 23.3 g
2. 82 g
3. 0.402 mol
4. 0.506 mol
Explanation:
We can convert moles (n) to mass (m) using the following expressions that include the molar mass (M).
n = m/M
m = n × M
1. The molar mass of NH₄Cl is 53.49 g/mol.
m = 0.436 mol × 53.49 g/mol = 23.3 g
2. The molar mass of Ca(NO₃)₂ is 164.09 g/mol.
m = 0.50 mol × 164.09 g/mol = 82 g
3. The molar mass of NaCl is 58.44 g/mol.
n = 23.5 g/(58.44 g/mol) = 0.402 mol
4. The molar mass of KMnO₄ is 158.03 g/mol.
n = 79.9 g/(158.03 g/mol) = 0.506 mol
<span>The correct answer is letter "d. It's used to make paper products." Cellulose is considered to be a major material used in creating a vast amount of paper products, such as papers, paperboards, and even cardboards. Cellulose can also be used as an important fiber as an important material in textiles.</span>
Oceanic crust is frequently pushed into the mantle near convergent plate borders, where it starts to melt. Granite, the rock that forms the continents, is formed as magma rises into and through the other plate.
Therefore, at convergent borders, oceanic and continental crust are annihilated.
<h3>What is a diverging plate boundary?</h3>
When plates are spreading apart, new oceanic crust is being created to fill the space left behind. Most divergent boundaries are observed around mid-ocean oceanic ridges (although some are on land).
The mountains would keep eroding over the next few million years, but since there wouldn't be any tectonic activity to renew them, they would gradually erode down to low rolling hills. This would result in far less fascinating geography and a flatter planet overall.

The number of hydrogen atoms is twice the number of oxygen atoms in ribose.
<h3>What is Ribose?</h3>
This is a sugar and a component of the ribonucleotides from which RNA is built. It has the formula C₅H₁₀O₅.
Ribose is a carbohydrate with the formula C₅H₁₀O₅. This molecule is a pentose monosaccharide which has a linear form
. The hydroxyl groups lie on the same side in the form of Fischer Projections.
The number of hydrogen atoms is double the number of oxygen atoms. The ribose sugar is found in the RNA.
It is the genetic material which is found in some organisms that carry information from one generation to another.
