The concentration in /mmolL of the chemist's silver(I) nitrate solution is 0.01047 mmoles/litre.
Explanation:
Data given:
Number of moles of AgNO3 in micro mole 4.7102micromol.
The concentration is supposed to be in mmol so the micromole will be converted to milimole.
So, 1 micromole = 0.001 millimole
hence, 4.712micromole will be 0.004712 millimole.
Volume is given as 450ml which is converted into L
to convert ml into L it is divided by 1000
so 0.45 L is the volume.
Molarity or concerntration is calculated by the formula,
molarity =
putting the values in the formula:
molarity =
= 0.01047 mmoles/litre is the molarity of AgNO3 solution in 450 ml of solution.
11.375 g ethylene is consumed if 35.0 grams of oxygen is allowed to react and 7.875 ml of water will be produced when the 35.0 grams of oxygen is allowed to react.
<h3>What are moles?</h3>A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
According to the chemical equation for the combustion of ethylene, 5
moles of oxygen are required to react with 2 moles of ethylene, hence
Similarly, 5 moles of oxygen are required as a reactant to produce 2 moles of water, thus
Given that the density of water is , therefore
The volume of water = 7.875 ml
