Why do scientists in the US use SI rather than the English system of measurements?
SI is used worldwide. As scientists, many of their ideas are going to be shared with colleagues within the US and overseas. Therefore, it's easier to use SI in order to keep the conversions to a minimum.
What is balanced force and unbalanced measured in?
In SI, forces are measured in Newtons.In SI, forces are measured in Newtons.In SI, forces are measured in Newtons.In SI, forces are measured in Newtons.
What is the oxidation number of H4SiO4?
+1 for each H, -2 for each O, +4 for Si
How many atoms of Si are in 237 g of Si?
237g / 28 gmol-1 = 8.46mol. 8.46 x (6.02x1023) = 5.09x1024 silicon atoms.
How many atoms are in 2.50 moles of Si?
2,50 moles of silicon contain 15,055352142.10e23 atoms.
How many atoms in CaAl2Si2O8?
There are 13 atoms:1 Ca atom2 Al atoms2 Si atoms8 0 atoms.
Calculate how many si atoms are contained in a transistor of a microprocessor of dimensions?
7
How many grams of silicon would there be in a sample that contained 9.991052 atoms?
1 mol of Si contains 6.02 x 1023 atoms (avogadro constant). Amount of Si = (9.99x1052) / (6.02x1023) = 3.75mol Molecular mass of Si is 28.1. Mass of Si = 3.75 x 28.1 = 105g
What is the distance between Si atoms in solid silicon?
2.22 angstroms is the distance between Si atoms in solid silicon.
What is the reaction of H2SiO4?
Silicic acid is H4SiO4; maybe that's what you want? That's SiO2 + 2H2O -> H4SiO4.
How many atoms are there in 6.26 g Si?
.250 mole 7.02 ------ 28.09 = .250
How many atoms are there in 100.0 moles of Si?
100 times Avogadro's Number = 6.022 X 1025.
Is there an SI unit for number of atoms?
No SI unit for no. of atoms. But there is a SI unit to measure the amount of any substance. It is moles and mole is a fixed quantity. Each mole represents a group of 6.022 x 1023 particles. These particles may be atoms or molecules.
How many ATOMS of silicon are present in 3.10 moles of silicon dioxide?
3.10 moles SiO2 (1 mole Si/1 mole SiO2)(6.022 X 1023/1 mole Si) = 1.87 X 1024 atoms of silicon =====================
