Answer is: 1635 <span>milliliters of carbon dioxide.
</span>n(CO₂) = 0,073 mol.
V(CO₂) = n(CO₂) · Vm.
V(CO₂) = 0,073 mol · 22,4 L/mol.
V(CO₂) = 1,635 L.
V(CO₂) = 1,635 L · 1000 mL/L.
V(CO₂) = 1635 mL.
Vm - molar volume on standard temperature and pressure.
Answer:
B. Convert mass percents to moles and then divide by the smallest mole value to get subscripts
Explanation:
The empirical formula is the smallest whole number ratio the elements in a compound can possess. According to this question, to derive the empirical formula of a compound from its percent composition of elements that make it up, the following steps are followed:
- First, since the elements are in percentage, one would assume the total mass of the compound is 100g and take each percentage as the mass of each element. For example, if a compound contains 16% oxygen, it means that 16g of oxygen is present.
- Next, we convert the mass of each element to moles by dividing the mass value by the molar mass of each element. For example, 16g of oxygen will be 16g/16g/mol = 1mol
- Next, we divide each mole value by the smallest mole value to get the subscript of each element that will be used in the empirical formula.
B because if more soot comes then the darker they will get.
Seeds come from adult plants. They're made from plants to make more plants.
