Is grams percent the same as grams per deciliter?
No. Grams percent is a mass-to-mass proportion whereas grams per decilitre is mass-to-volume. They will be the same if the two things have the same density but there can be very large differences if the densities are different.
What compound has a lower percent of mass by nitrogen- NO or N2O3?
The oxide N2O3 has a lower percent of mass nitrogen.
If 40 percent of the isotopes of an element have a mass of 16 atomic mass and 60 percent of the isotopes have a mass of 18 atomic mass what is the average atomic mass?
((16x40) +(18x60))/100 = 17.2
If 75 percent of the isotopes of an element have a mass of 35.0 amu and 25 percent of the isotopes have a mass of 37.0amu what is the atomic mass of the element?
35.5 amu
What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

What is average atomic mass of 75.47 percent and a mass of 248.7 amu and 24.53 percent and mass of 249.4 amu?
the amu is 248.863 all u do is for each one the mass × percent divided by a 100 if there is more u do the same and add them together
Is the percent by mass of copper in CuSO4 5H2O the same as in CuSO4?
No. The % of Cu by mass in CuSO4 will be greater than the % of Cu by mass in the pentahydrate (5H2O) because in the hydrate there is added mass (5 H2O = 90 g) but no added Cu.

Bernard's star has a mass of how many times the mass of sun?
15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.15-17 percent of the mass of the Sun.
Why is it inaccurate to say that CO is 50 percent oxygen?
Because the mass of carbon is not the same as that of oxygen.
What is the equation used to calculate percent by mass?
Percent by mass = (100) times (mass of the ingredient of interest) divided by (mass of the whole mixture)
Determine the percent sulfur by mass in so3?
the percent sulfur by mass in so3 is 40.050%
What is the mass percent of oxygen in of N2O4?
The percent by mass of oxygen in N2O4 is 69,56 %.
Does the compounds C2H2 and C6H6 have the same percent composition by mass?
It does not necessarily mean that. For example glucose (C6H12O6) and formaldehyde (CH2O) have the same percentages of elements by mass, but are two very difference compounds.
What is the mass percent of chlorine in CCl3F?
77.42% mass of chlorine / mass of entire chemical x 100 = percent composition
What is the difference of percent of mass and percent of volume?
Percent of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.
What is the formula of the percent of volume and percent of mass?
% of volume = 100*(volume of substance that you are interested in)/(total volume) % of mass = 100*(mass of substance that you are interested in)/(total mass).
