1. The student didn’t push with enough force ._.
<h3>
Answer:</h3>
48.95% (m/v)
<h3>
Explanation:</h3>
From the question we are given;
- Mass of solute, NaCl is 186 g
- Volume of the solvent, water as 3.80 L or 380 mL
We are required to calculate the mass volume percent of solution;
How do we calculate the mass volume percent of a solution?
- To calculate the mass volume percent, we use the formula,
Mass volume percent = (mass of solute in g/Volume of solvent in mL) 100
= (186 g ÷ 380 mL)100
= 48.95%
Therefore, the mass volume percent of a NaCl solution is 48.95% (m/v).
Answer:
Explanation:
Boyle's law states that at constant temperature:
P
PV = constant
Where: P is the pressure of a given mass of gas, and V is its volume.
The bubble wrap has a confined volume of air at constant temperature. Since a gas is easily compressible, the volume of the gas in the wrap decreases with increasing pressure. This implies that there is an inverse proportion relation between the pressure on and volume of the air.
The bubble wrap pops when stepped onto or squeezed because the pressure is high and the volume can not be compressed further. Thus, the elastic limit of the seal is exceeded. This leads to an escape of the confined air.
