Given that the molar mass of carbon is 12 g/mol and the molar mass of oxygen is 16 g/mol, calculate the molar mass of carbon dio
nekit [7.7K]
Molar mass of oxygen is:
M(O)=16 g/mol
Molar mass of carbon is:
M(C)=12 g/mol  
Molar mass of carbon dioxide is:
M(CO2)=M(C)+2*M(O)
 M(CO2)=12 g/mol+2*16g/mol
M(CO2)=44 g/mol

<span>Molar mass(M) is the mass of 1 mole of the substance (grams per mole of a compound).</span>

Iodine 131, cesium 137, and strontium 90 are all considered isotopes. What are isotopes?
Nitella [24]

Answer:

Isotopes are variants of an element, where the number of neutrons is different but its number of protons stay the same.

Explanation:

If the number of protons had changed then it would just be a different element.

Electron number changing simply adds charge to the atom, and doesn't change it or anything.

P4O10 -&gt; 4P+5O2 How many moles of phosphorus would be produced if 5.3 mol of P4O10 reacted?
viktelen [127]

Answer:

21.2 moles.

Explanation:

Hello!

In this case, for the given chemical reaction, we can see there is a 1:4 mole ratio between tetraphosphorous decaoxide and phosphorous; therefore, the following proportional factor provides the requested moles of phodphorous:

n_P=5.3molP_4O_{10} *\frac{4molP}{1molP_4O_{10}} \\\\n_P=21.2molP

Best regards!
