Heterotrophic cells must ingest biomass to obtain their energy and nutrition. Heterotrophic microorganisms mostly feed upon dead plants and animals, and are known as decomposers. ... Some animals also specialize on feeding on dead organic matter, and are known as scavengers or detritivores. Hope this was helpful.
I can easily work out the molar mass of Ca3PO4 - but I do not see any reason to do this.
There is no such compound
If you want the molar mass of tricalcium phosphate , then the correct formula is Ca3(PO4)2 .
For purposes of calculating the molar mass it is easier to write: Ca3P2O8
Ca = 40.078g/mol *3 = 120.234g
P = 30.974g/mol *2 = 61.948g
O = 15.999g/mol *8 = 127.992g
Total = 310.174g/mol
Mass of 4.5 mol = 310.174g/mol *4.5mol = 1395.783g

Answer:
C₆H₁₈
Explanation:
Let's say x is the subscript of carbon and y is the subscript of hydrogen. We know from the empirical formula that the ratio of x to y is 2 to 6.
x / y = 2 / 6
We also know from the molar mass that:
12.01x + 1.01y = 90.21
Solving the system of equations:
2y = 6x
y = 3x
12.01x + 1.01(3x) = 90.21
12.01x + 3.03x = 90.21
15.04x = 90.21
x = 6
y = 3x
y = 18
The molecular formula is therefore C₆H₁₈.

The correct formula of a compound that has ten oxygen atoms and four phosphorus atoms will be
<u>(tetra phosphorus decoxide)</u>
<u />
Chemical element symbols, numbers, and other symbols, such as parentheses, dashes, brackets, commas, plus as well as minus signs, are used to represent the chemical quantities of the atoms that make up a certain chemical compound and molecule.
It is given that the number of P atom is 4 and 10 oxygen . Decoxide mean
any oxide with ten oxygen molecules per molecule.
Typically, a molecular molecule consists of two or even more nonmetal components. Molecular compounds are characterized by employing the stem of the primary element's term plus the suffix -ide, followed by the second element. The count of atoms in a molecule is specified using numerical prefixes.
Therefore, The correct formula of a compound that has ten oxygen atoms and four phosphorus atoms will be
<u>(</u><u>tetra phosphorus decoxide)</u>
