A carnivore is something that eats meat so C. spider would be a Carnivore
Hope i helped :)
<span>The formula for mass, which is mass = density x volume, can be rewritten as volume = mass/density. We can deduce the volume of the cube as the mass and density are given: 17.2g/2.7g/ml = 6.37ml. Now that the volume of the cube is known, we can deduce the edge length. Volume = length x width x height, so 6.37 = X^3. We then take the cube root of 6.37 to discover the value of x, which will be the edge length of the cube. The edge length of the cube is 1.85 cm.</span>
Answer:
0.12 g/L
Explanation:
We first calculate its molar mass M = solubility at STP × molar volume = 0.14 g/L × 22.4 L/mol = 3.14 g/mol
Using the ideal gas law, PV = mRT/M where P = pressure at STP = pressure at 50°C = 1 atm, V = volume of gas, m = mass of gas, R = molar gas constant = 0.082 atm L/mol-K, T = temperature of gas = 50°C = 273 + 50 = 323 K and M =molar mass of gas = 3.14 g/mol
So, PM/RT = m/V = solubility of gas at 50°C
So, PM/RT = 1 atm × 3.14 g/mol/(0.082 atm L/mol-K × 323 K)
= 3.14 atm g/mol ÷ 26.486 atm L/mol
= 0.119 g/L
≅ 0.12 g/L
Answer:
386.66 g/mol
Explanation:
To calculate the molar mass of a molecule, you add up the molar masses of its atoms.
Thus, for cholesterol. we get
27C = 27 × 12.011 = 324.297 g
46H = 46 × 1.008 = 46.368
1O = 1 × 15.999 = <u> 15.999
</u>
TOTAL = 386.655 g
To two decimal places, the molar mass of cholesterol is 386.66 g/mol
