The specific heat capacity of oat drink is 3900 J/kg ∘C3900 \text{ J/kg }^\circ\text{C}3900 J/kg ∘C.
The specific heat capacity of water is 4200 J/kg ∘C4200 \text{ J/kg }^\circ\text{C}4200 J/kg ∘C.
The specific latent heat of condensation of steam is 2260 kJ/kg.
The temperature of the steam is 100∘C100^\circ\text{C}100∘C.
The mass of steam that condenses into the drink is 20 g.
The temperature of the oat drink rises from 10∘C10^\circ\text{C}10∘C to 70∘C70^\circ\text{C}70∘C.
By considering the total thermal energy transferred from the steam as it condenses and then cools to 70∘C70^\circ\text{C}70∘C, calculate the mass of the oat drink that is heated. Give your answer to 3 significant figures.
