What is the volume in liters of 3.80 moles of CO2gas at STP?
pantera1 [17]

Answer:

V = 85.2

Explanation:

STP = 273K and 1 atm

Considering what we know about STP, we get the moles, temperature, and pressure. Using the ideal gas law we can find the volume (PV = nRT). Plug in our variables: (1 * V = 3.80 * R * 273). Since we are dealing with atm and not kPA or mmHg, we use the constant for atm (0.0821) which we use for R. (So.. now our equation is 1 * V = 3.80 * 0.0821 * 273). We now multiply the right side to get 85.17054. So... V = 85.2 considering sigificant figures (this is the part where I am the least sure of, since I havent done sig figs in a while)

Convert 0.00200 g into Mg and answer in scientific notation:
Masja [62]

Answer: 2.00x10^{2}

Explanation: 1 gram is equal to 1000 Milligrams so

0.00200g=\frac{1000mg}{1g}

Since you go straight across its just multiplication so 0.00200x1000=200mg

To answer it in scientific notation it should just be 2.00x10^{2} mg
