2) In a calorimetry experiment, 70.0 g of a substance was heated to
Aloiza [94]

The temperature at thermal  equilibrium : 16.1 °C

<h3>Further explanation</h3>

Q absorbed = Q released

Heat can be formulated :

Q = m.c.Δt

c= specific heat, J/g°C

Δt = temperature different, C°

m= mass, g

Q water=Q substance

\tt 3500\times 4.18\times (t_2-15)=70\times 0.89\times (270-t_2)\\\\14630(t_2-15)=62.3(270-t_2)\\\\14630t_2-219450=16821-62.3t_2\\\\14692.3t_2=236271\\\\t_2=16.1^oC

A rectangular container of air measures 1.2 x 10-2 m by 8.34 x 10 1 m by 6.0 x 10-1 m. Air
Dominik [7]

The volume of the rectangle has been given by the product of length, breadth, and height. The mass of the air with a density of 1180 g/m³ is 708.57 gms.

<h3>What is density?</h3>

The density of the substance has been known to be given by the mass's ratio to the volume. The formula for density is given as,

Density = Mass ÷ Volume

Given,

Density = 1180 g/m³

The volume of the rectangle = L×B×H

Substituting the values above,

Mass = Density × Volume

M = 1180 × 1.2 × 10⁻² × 8.34 × 10¹ × 6.0 × 10⁻¹

= 708.57 gm

Therefore, the mass of the air is 708.57 gms.
