Explanation:
I'm pretty sure 1. yes 2. no and 3. it might be yes but I'd just put a maybe
Since the given formula is . According to cross method formula, magnesium has +2 charge so, is multiplied by 2.
Thus, 1 molecule of magnesium phosphate will contain 2 atoms of phosphorus.
Therefore, three molecules of magnesium phosphate contains following number of atoms.
Mg = 9
P = 6
O = 24
Hence, we can conclude that there are 6 atoms of phosphorus in three molecules of magnesium phosphate, .
Answer:
A. 15859.2 L or 15900 L
B. 0.629 mol
Explanation:
At STP, one mole is equal to approximately 22.4 L
L or mL is volume, so you are attempting to solve for L or mL.
A.
708 mol x (22.4 L/1 mol) = 15859.2 L (w/ significant figures included - 15900 L)
B.
(14.1 L) x (1 mole/ 22.4 L) = 0.629 mol.
Answer:
These predictions are likely to be valid and should be needed.
Explanation:
Meteorologist made predictions about weather of a particular area on the data they received from the satellite. Meteorology is a branch of science in which we study about the atmosphere. It is mainly used for the forecasting of weather and meteorologists are those people or scientists who study the weather and research on different scales or instruments of weather.
Mass fraction has been the mass of an individual element with respect to the compound. The mass fraction of chloride in calcium chlorate is 0.171.
<h3>What is meant by a mass fraction?</h3>
Mass fraction has been defined as the ratio of the masses of the individual elements present in a compound to the total mass of the molecule or compound.
The formula for a mass fraction (w) is given as,
Mass fraction (w) = mass ÷ total mass
Given,
Mass of chlorine = 35.453 grams per mole
The molar mass of calcium chlorate (Ca(ClO₃)₂) = 206.98 grams per mole
Substituting and solving the values above as
w = mass of chlorine ÷ total mass of calcium chlorate
w = 35.453 ÷ 206.98
w = 0.171
Therefore, the mass fraction of Cl in calcium chlorate is 0.171.
