Answer: The molecular formula will be
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
Empirical weight of is
Molecular mass of compound is = 132 g
Now we have to calculate the molecular formula.
The molecular formula will be=
We have 30% (w/w) HCl this means :
100 g solution contains 30 g HCl
?? g solution contains 7.5 g HCl
By cross multiplication:
Mass of solution =
= 25 g solution
Answer:
4.7 × 10⁴ J
Explanation:
Step 1: Given data
- Initial temperature: 25 °C
- Final temperature: 100 °C
- Specific heat capacity of water (c): 4.184 J/g.°C
Step 2: Calculate the temperature change (ΔT)
ΔT = 100 °C - 25 °C = 75 °C
Step 3: Calculate the heat required (Q) to raise the temperature of the water
We will use the following expression.
Q = c × m × ΔT
Q = 4.184 J/g.°C × 150 g × 75 °C = 4.7 × 10⁴ J
