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.
Percent composition is expressed as a percent by?
Percent composition is usually expressed as a percent by mass, but in the case of gases and vapors, it is often expressed as a percent by volume.
What compound has a lower percent of mass by nitrogen- NO or N2O3?
The oxide N2O3 has a lower percent of mass nitrogen.
What is the mass percent A compound contains 14.5 g of magnesium and 3.5 g of oxygen. What is the mass percent of oxygen in the compound?
To find the mass percent of oxygen in the compound, first calculate the total mass of the compound by adding the masses of magnesium and oxygen: 14.5 g + 3.5 g = 18.0 g. Then, use the formula for mass percent: (mass of oxygen / total mass) × 100%. Thus, the mass percent of oxygen is (3.5 g / 18.0 g) × 100% ≈ 19.44%.
The percent by mass of hydrogen in NH3 is equal to?
The percent by mass of hydrogen in NH3 is 17.65%. This can be calculated by dividing the mass of hydrogen in NH3 by the total mass of NH3 and then multiplying by 100.
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 mass percent and weight percent same?
Yes, mass percent and weight percent are generally considered the same when working with everyday units. Both refer to the proportion of a specific component in a mixture relative to the total mass or weight of the mixture, often expressed as a percentage. However, there may be subtle differences in scientific contexts where weight is used to refer to mass influenced by gravity.
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.
Is the percent by mass of copper in CuSO4 5H2O the same as in CuSO4?
No, the percent by mass of copper in CuSO4 5H2O will be different than in CuSO4 because CuSO4 5H2O includes water molecules in addition to the copper sulfate compound itself. Therefore, the total mass of CuSO4 5H2O will be greater, resulting in a lower percent by mass of copper in CuSO4 5H2O compared to CuSO4.
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.
A sugar solution of 35.8g sugar and 125.35g of water. what is the percent by mass of the sugar and the percent by mass of the water in the solution?
add 35.8g sugar to 125.35g of water this = 100% of the solution. then divide 35.8g of sugar by the whole solution and multiply by 100 to get the percentage (35.8)/ (125.35 + 35.8)= .222 * 100= 22.2% sugar is 22.2% of the solution. Do the same for the water switch 35.8 by 125.35
Percent composition is expressed as a percent by?
Percent composition is usually expressed as a percent by mass, but in the case of gases and vapors, it is often expressed as a percent by volume.
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)
What is the mass percent of oxygen?
The mass percent of oxygen is approximately 21% in Earth's atmosphere.
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 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.
