Answer:

Ohm's law states that Voltage is directly proportional to the Current passing through the conductor. It increases in case of conductors and decreases in case of semi-conductors. Hence Resistivity turned out to be a variable making the Resistance a variable too and hence proving Ohm's Law wrong.

The equation for density, d, is

ss7ja [257]

<u>Answer:</u> The density of substance is $3.38g/cm^3$

<u>Explanation:</u>

To calculate density of a substance, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

We are given:

Mass of substance = 61.6 g

Volume of substance = $18.2cm^3$

Putting values in above equation, we get:

$\text{Density of substance}=\frac{61.6g}{18.2cm^3}\\\\\text{Density of substance}=3.38g/cm^3$

Hence, the density of substance is $3.38g/cm^3$

The concentration after dilution is 1.4%.

We are aware that concentration and volume are related to each other by the formula -

$C_{1}$ $V_{1}$ = $C_{2}$ $V_{2}$ , where we have initial concentration and volume on Left Hand Side and final concentration and volume on Right Hand Side.
