How do you write 4.1 percent as decimal?
Converting a percent to its decimal equivalent is done by dividing by 100: 4.1 ÷ 100 = 0.041
Weight of 90 percent gasoline and 10 percent ethanol?
5.75 lbs
What is 0.5 percent As a decimal in simplest form?
Converting a percent to its decimal equivalent is accomplished by dividing by 100 (or moving the decimal two places to the left): 0.5 ÷ 100 = 0.005
How is 7 percent written as a decimal?
Converting a percent to its decimal equivalent is accomplished by dividing by 100 (the same as moving the decimal two places to the left): 7 ÷ 100 = 0.07
How do I turn 6500 sq ft into tons?
You are talking about area and weight, you can't convert them. It would be like converting apples to oranges.
What is the difference between atomic percent and weight percent?
Atomic percent is based on the number of atoms in a sample. So if the sample has x number of oxygen atoms and x number of iron atoms it would report 50% oxygen and 50% iron (atomic percent). Weight percent is based on the mass of the elements detected. So if we used the above example and reported the results as weight percent we would get 22.3% oxygen and 77.7% iron. Weight percent takes into consideration the mass or atomic weight of the elements and not just the number of atoms. Most people use weight percent although for chemistry atomic percent may be more useful.
What is the weight percent of carbon in CH4?
Carbon has a atomic mass of 12.So its percentage is 75%
How is percent composition by mass determined?
For a chemical compound, ex. ABC: Percent (%) of A is (atomic weight of A x 100)/molecular weight of ABC.
How much chromium is in a 70 percent by weight concentration of sodium dichromate?
Cr2Na2O7 Atomic Weight Cr - 51.996 Atomic Weight Na - 22.98977 Atomic Weight O - 15.9994 Atomic Weight Cr2Na2O7 - 261.96734 Atomic Weight Cr2 - 103.992 at 100% concentrationCr2 - Cr2Na2O7 = (103.992/261.96734)*100 = 39.70% Cr in Cr2Na2O7 at 70% concentration = 39.70*70%= 39.70*.70 = 27.79% Cr in Cr2NaO7 at 70% concentraion.
How do you calculate the atomic weight of a chemical element that has two or more isotopes?
To calculate the atomic weight of an element with multiple isotopes, you multiply the mass of each isotope by its relative abundance (as a decimal), then sum the products. The result is the atomic weight of the element, which is a weighted average of the masses of its isotopes based on their abundance in nature.
What is the automic mass of chlorine atom?
Chlorine 35: exact weight: 34.968852, percent abundance: 75.77 Chlorine 37: exact weight: 36.965903, percent abundance: 24.23 average atomic weight; 35.453
How is converting a ratio to percent the same as solving a proportion?
Converting a ratio to a percent is not the same as solving a proportion.
Converting percent to decimal?
Divide the percent by 100.
What is chemical atomic weight?
Atomic weight = Weight of protons + Weight of neutrons
One has an atomic weight of 120.9038 amu with 57.25 percent abundance the other has an amu of 122.8831 what is the atomic weight of the element?
To calculate the atomic weight of the element, you need to consider the weighted average of the two isotopes based on their abundance. Atomic weight = (atomic mass isotope 1 * abundance isotope 1) + (atomic mass isotope 2 * abundance isotope 2) Plugging in the values: Atomic weight = (120.9038 amu * 0.5725) + (122.8831 amu * 0.4275) = 69.17 + 52.6 = 121.77 amu.
What is a synonym for atomic mass?
Unified atomic mass unit
What is carbons atomic weight?
Atomic Number = 6. Atomic Weight = 12.011
