the density of gas was done twice, but with the tablet and 15 cm^3 of water in each case.When the rubber tube was placed as shown , 435 cm^3 of gas was collected. When the tube reached only slightly beyond the mouth of the bottle, only 370 cm^3 of gas was collected. The change in mass of the reactant was the same in both cases.
What volume of gas dissolved in water?
What mass of gas dissolved in water?
To find the volume of gas dissolved in water, you need to subtract the volume collected in both cases from the initial volume of gas.
Initial volume of gas = 435 cm^3 (first case) + 370 cm^3 (second case)
= 805 cm^3
Volume of gas dissolved in water = Initial volume of gas - Volume collected
= 805 cm^3 - 435 cm^3 (first case) - 370 cm^3 (second case)
= 805 cm^3 - 805 cm^3
= 0 cm^3
Therefore, no gas was dissolved in water in both cases.
To find the mass of gas dissolved in water, you need more information, such as the density of the gas. Without the density, it is not possible to calculate the mass of gas dissolved in water. Could you provide the additional information?
To find the volume and mass of gas that dissolved in water, we need to first understand the relationship between the volume of gas collected and the density of the gas.
Let's break down the information given:
1. In the first case, when the rubber tube was placed as shown, 435 cm^3 of gas was collected.
2. In the second case, when the tube reached only slightly beyond the mouth of the bottle, only 370 cm^3 of gas was collected.
3. The change in mass of the reactant was the same in both cases.
From this information, we can deduce that the difference in the volume of gas collected (65 cm^3, which is 435 cm^3 - 370 cm^3) represents the volume of gas that dissolved in water.
Now, to find the mass of gas that dissolved in water, we need to consider the density of the gas. However, the given information does not provide direct information about the density.
To find the mass of gas dissolved in water, we could use the ideal gas law equation (PV = nRT), where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature. However, without further information about pressure, temperature, or number of moles, we cannot directly calculate the mass of the gas.
Therefore, the answer to both questions ("What volume of gas dissolved in water?" and "What mass of gas dissolved in water?") cannot be determined with the given information.
