Answer: The mass of aluminium sample is 55.4 gram
Explanation:
As we know that,
where,
= mass of aluminium = ?
= mass of water = 300.0 g
= final temperature =
= temperature of aluminium =
= temperature of water =
= specific heat of aluminium =
= specific heat of water =
Now put all the given values in equation (1), we get
Therefore, the mass of aluminium sample is 55.4 gram
