In lab you reacted 60 grams of propane (C3H8) with 13 grams of oxygen gas (O2). Your
Andre45 [30]

Answer:

120g

Explanation:

Based on the reaction, when 1 mole of propane and 5 moles of oxygen react, 3 moles of CO2 and 4 moles of H2O are produced. The ratio of production is 3 moles of CO2 per 4 moles of H2O.

Thus, we need to convert mass of water to moles using its molar mass:

Moles H2O (Molar mass: 18g/mol):

63g H2O * (1mol / 18g) = 3.5 moles H2O

Converting to moles of CO2:

3.5 moles H2O * (3 moles CO2 / 4 moles H2O) = 2.625 moles CO2

Mass CO2 (Molar mass: 44g/mol):

2.625 moles CO2 * (44g / mol) = 115.5g of CO2 are released

<h3>120g </h3>

What are two methods to solve the energy crisis?​

Possible Solutions to the Problem of Global Energy Crisis

Buy Energy-Efficient Products. ...

Perform Energy Audit. ...
Common Stand on Climate Change. We've got to reduce our dependence on foreign oil; it's a matter of homeland security. Fine. Nobody's arguing. But the solutions that get offered -- drilling in ANWR, mandating better automobile fuel efficiency, pushing ethanol -- don't really solve anything. They're politically impossible, or too expensive, or contrary to free-market forces. They're losers.
Energy-independence advocate Gal Luft looks for winners. The former lieutenant colonel in the Israel Defense Forces and counterterrorism expert fervently believes that the only way to make America safe is to make it energy independent. And so as executive director of the Institute for the Analysis of Global Security and cofounder of the Set America Free Coalition, he has set out to do just that.

Luft advises Congress and security companies. He briefs industrial and environmental groups. Yet what separates him from other energy specialists are his pragmatic solutions. He doesn't peddle pie-in-the-sky political strategies. He's a realist. He has a single goal: freeing America from the grip of foreign oil. And he wants to do it now. At right are four steps he says we can -- and should -- take today.
