A small electric immersion heater is used to heat 57 g of water for a cup of instant coffee. The heater is labeled “190 watts” (it converts electrical energy to thermal energy at this rate). Calculate the time required to bring all this water from 24°C to 100°C, ignoring any heat losses. (The specific heat of water is 4186 J/kg·K.)
How can I solve this problem?

A small electric immersion heater is used to heat 57 g of water for a cup of instant coffee. The heater is labeled "140 watts" (it converts electrical energy to thermal energy at this rate). Calculate the time required to bring all this water from 22°C to 100°C, ignoring any heat losses. (The specific heat of water is 4186 J/kg-K.) Number Units the tolerance is +/-2%
