MISSED THIS? Watch KCV TOZ WEE ro itt Read Sochon fo: You can click on the Reviow hink to adcess the sechion in jour e fout: The zone wichin a copper-plated penry will dissolve in tydrochloric ackd it the copper coating is filed down in several apots iso that the fydrochloric acid can get to the zinc). The reoction between the actid and the zinc is as follow: $2{\mathrm{H}}^{\prime }(\mathrm{aq})+\mathrm{Zn}(\mathrm{s})\to {\mathrm{H}}_2(\mathrm{s})+{\mathrm{Zn}}^{2+}(\mathrm{aq})$ When vhe zino in a cortain penny dissolvos, the total volume of gas collected over water at $25^{\circ }\mathrm{C}$ was $0.961\mathrm{L}$ at a total pressure of $750\mathrm{mm}{\mathrm{mg}}_{\mathrm{g}}$. Vapor pressure of water versus temperature What mass of hydrogen gas was collected? Express your answer in grams to three significant figures. * Incorrect; Try Again; 5 attempts remaining Use the ideal gas law to find the amount of hydrogen gas in moles: $PV=nR$ where $P$ is the pressure in atm of hydrogen gas, $V$ is the volume in L, $n$ temperature in K. Recall that, according to Dalton's law, the total pressure components. This definition can be used to calculate the partial pressure of to its mass, using the molar mass (in units of $\mathrm{g}/\mathrm{mol}$ ) as a conversion factc
