Hey there!
Cr₄(P₂O₇)₃
Cr: 4 x 51.996 = 207.984
P: 6 x 30.97 = 185.82
O: 21 x 16 = 336
-------------------------------------
729.804 g/mol
The molar mass of Cr₄(P₂O₇)₃ is 729.804 g/mol.
Hope this helps!
The volume of a gas can be found by using ideal gas formula. The formula would be:
V= nRT/P
where
n= number of the molecule (mol)
R= constant
T= temperature
P= pressure
Then, the answer would be
<span>1. temperature
2. pressure
3. mass
4. number of molecules </span>
It's the D. Skin hope you understand
Answer:
2
Explanation:
The compound H2CCH2 has the condensed formula C2H4. The name of the compound is ethene. The compound is unsaturated, that is, it contains multiple bonds. The compound has a formula which fits into the general molecular formulae of alkenes (olefins) which his CnH2n.
Olefins have a double bonds between the carbon atoms. That is , the two carbon atoms in Olefins are connected via a double covalent bond. This now implies that the two carbon atoms in ethene (C2H4) are connected by two covalent bonds in the lewis structure of the molecule as is common for Olefins.
