What those this best represent Dalton’s law Charles law
lubasha [3.4K]
Ideal Gas Law

Charles Law is a given volume mass of gas varies directly with the kelvin temperatures when the volume remains constant.

Daltons' Laws is, that at constant temperature, and pressure, the pressure of a mixture of gases that doesn't interact will be the sum of pressures of individual gases.




Hope that helps!!!

Assuming your weight is 440.55 N and the force of gravity on Earth is 9.8 m/s2 what is your mass? *
Alexandra [31]

Answer:

44.95408163 kg

44.95 kg (2 decimal places)

Explanation:

Weight=Mass*Gravity

440.55=m*9.8

Make m the subject

M=440.55/9.8

M= 44.95 kg

When a 5.00-g metal piece, A, was immersed in 38.0 mL of water, the water level rose to 50.0 mL. Similarly, when a 5.00-g metal
Mnenie [13.5K]

Answer:

A is denser than B as it's volume for the same mass is smaller.

Explanation:

Hello.

In this case, we first need to take into account that the density of each metal A and B is computed by dividing the mass over the volume of each metal which is actually computed by substracting the volume of water from the volume of the water and the solid:

V_A=50.0mL-38.0mL=12.0mL\\\\V_B=60.0mL-38.0mL=22.0mL

Next, we compute the densities as shown below:

\rho_A=\frac{m_A}{V_A}=\frac{5.00g}{12.0mL}=0.42g/mL\\  \\\rho_B=\frac{m_B}{V_B}=\frac{5.00g}{22.0mL}=0.23g/mL

In such a way, A is denser is B as it's volume for the same mass is smaller.

Best regards.
