An engineer investigated the energy transferred to a copper block by burning different gas fuels using a specialized burner.
| Fuel | Initial mass of cylinder in g | Final mass of cylinder in g | Mass of fuel burned in g |
|---|---|---|---|
| Methane | 245.80 | 243.62 | 2.18 |
| Ethane | 278.15 | 276.03 | 2.12 |
| Propane | 312.40 | 310.45 | |
| Butane | 350.55 | 348.73 | 1.82 |
The results show that 2.12 g of ethane was needed to raise the temperature of the copper block by 35 ∘C35\text{ }^\circ\text{C}35 ∘C.
Calculate the mass of ethane needed to raise the temperature of the copper block by 1 ∘C1\text{ }^\circ\text{C}1 ∘C.
