What is the mass of 2.6 g of magnesium and 1.6 g of oxygen?
The molar mass of magnesium is 24.31 g/mol, while the molar mass of oxygen is 16 g/mol. To find the mass of 2.6 g of magnesium, you can divide 2.6 g by the molar mass of magnesium (24.31 g/mol) and multiply by Avogadro's number to find the number of moles. Similarly, you can do the same calculation for 1.6 g of oxygen and then sum up the molar masses to find the total mass.
How many molecules are in 10.0 g of pure C8H8O3?
To determine the number of molecules in 10.0 g of C8H8O3, we need to calculate the number of moles first. The molar mass of C8H8O3 is 152.15 g/mol. By dividing 10.0 g by the molar mass, we find that there are approximately 0.0658 moles of C8H8O3. To convert moles to molecules, we multiply the number of moles by Avogadro's number, 6.022 x 10^23, giving us about 3.96 x 10^22 molecules.
How is a number of moles of an element determined from a known mass?
The number of moles is mass in g/molar mass in g.
How many grams is one square of chocolate on average specifically lindt milk fruit and nut?
Look on the wrapper. Find the number of grams in the whole bar. Write down the number, and call it 'G'. Now tear the wrapper open and expose the whole bar. Count the number of squares in it. Write down the number and call it 'S'. Divide 'G' by 'S'. In other words, calculate the number that's equal to (G/S). That quotient is the average number of grams per square in that bar.
Do atom orbitals contain thousands of electrons or just a few electron?
If you look at a periodic chart, you will see that each element has a number. That number gives the number of protons and electrons that each element contains. There are limits to the number of electrons that any orbital can contain. The orbitals are labeled: s, p, d, f, g, h, i, k. The first two atoms in the periodic table, Hydrogen and Helium, only have an s orbital. The s orbital holds two electrons. When the s orbital is full, as with Helium, it can not react with anything else. Helium is inert. The next row in the periodic table contains the p orbital. When the p orbital is full, as in Neon, then it can not react. If you look at the periodic table, the orbitals can hold more electrons and each element can hold more orbitals. If it becomes possible to create an element with several hundred protons, the orbitals could hold many electrons.

What is the maximum number of electrons that can occupy 5d subshells?
In any shell excluding shell1, there is only 1 s orbital and 1 p orbital. Subshells and the Orbitals are same. Orbital g is known as subshell 5. g orbital is present shell 6. But till today no element is discovered with an electron in g orbital.
Where can you find a solution to problem solving number of moles in a given element?
Number of moles = Mass of the sample in g/Molar mass in g
How much does a 2008 penny weight?

What is the diameter of a penny in millimeter and its mass in grams?
English penny of today: 3,56 g and 20,32 mm.
Maximum number of electrons in the 5s orbital?
2. Two electrons of opposite spin. This is true of all s, p, d, f g.... orbitals, eah can only contain two electrons of opposite spin.
Find the number of moles in 607 g krypton?
7.24 moles.

What is the maximum number of electrons that can occupy the 6s subshell?
6th energy level can hold 72 electrons. (has s,p,d,f,g, and h subshells)
How many electrons are in the g sublevel?
There are 9 orbitals in a g sublevel. (there is 1 in an s sublevel, 3 in a p sublevel, 5 in a d sublevel, 7 in an f sublevel, 9 in a g sublevel, 11 in an h sublevel, etc.)
What is the mass of 2.6 g of magnesium and 1.6 g of oxygen?
The molar mass of magnesium is 24.31 g/mol, while the molar mass of oxygen is 16 g/mol.

How many moles of SO2 are present in 250.0 g?
Number of moles is determined by dividing molar mass into the number of grams. SO2 has a molar mass of 64.066 g. To find the number of moles in 250.0 g of SO2, divide 250.0 g by 64.066 g. This gives you just over 3.9 moles.
