The grams of hydrogen gas can be burned if 40. liters of oxygen at 200. k and 1.0 atm is 4.88 grams.
<h3>How do we calculate grams from moles?</h3>
Grams (W) of any substance will be calculated by using their moles (n) through the following equation:
M = molar mass
And moles of the gas will be calculated by using the ideal gas equation as:
P = pressure = 1atm
V = volume = 40L
n = moles = ?
R = universal gas constant = 0.082 L.atm / K.mol
T = temperature = 200K
On putting these values on the above equation, we get
n = (1)(40) / (0.082)(200) = 2.439 = 2.44 moles
- Now grams of hydrogen gas will be calculated by using the first equation as:
W = (2.44mol)(2g/mol) = 4.88g
Hence required mass of hydrogen gas is 4.88g.

Answer:
Translucent objects allow some light to travel through them
Explanation:
Materials like frosted glass and some plastics are called translucent. When light strikes translucent materials, only some of the light passes through them
Answer:
4 significant digits
Explanation:
Zeroes placed between other digits are always significant
We would be using less natrual resources in both the packaging and process of making the packaging, which includes:
-Gas to import and export goods
-Plastics
-Paper (trees)
-Animal Furs
etc.
