A compound is 57.1% oxygen and the remainder carbon. using oxygen as the standard (16 amu) and assuming a 1:1 atom ratio, calcul
Delicious77 [7]
Let's start with the amount given in percent. Let our basis be 100 grams of compound. So, that means that in this amount, 57.1 g is oxygen and 100-57.1=42.9 g is carbon. Since there is 1:1 atom ratio, it also means that moles oxygen = moles carbon.

Moles = Mass/Relative Mass
Let x be the relative mass of oxygen

57.1/16 = 42.9/x
Solving for x,
<em>x = 12.02 amu</em>

PLEASE I NEED HELP!!!Using the table below, identify the unknown material that has a mass of 15,06 g and a
s2008m [1.1K]

The unknown material : gold

<h3>Further explanation  </h3>

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

Density formula:  

\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}

ρ = density  

m = mass  

v = volume  

mass of unknown material : 15.06 g

volume : 0.78 ml

The density of unknown material :

\tt \rho=\dfrac{15.06}{0.78}\\\\\rho=19.31~g/ml

Materials that match the density: gold
