Comparing quantum computers to supercomputersis mostly a matter of degree, since supercomputers use the same semiconductor circuitry and binary logic as classical computers. But they multiply those classical ca
That's how many joules (the standard measurement of energy) you'd get from a kilogram of mass. In theory, if you could turn about seven billion hydrogen atoms completely to energy, you'd get about one joule (that's about as much energy as a 10-watt lightbulb consumes in a tenth of...
If a student weighs 18 g of aluminum and needs twice as many atoms of magnesium as she has of aluminum, how many grams of Mg does she need? How many moles of silver (Ag) atoms are there in 3.80 \times 10^{24} silver ...
The average mass of the atoms that make up Earth is 40 u. How many atoms are there in Earth? Mass: In physics, the term mass can be defined as the measuring of the amount of matter that any object consists of. The mass directly...
Light can be trapped — and even stopped — inside ultra-cold clouds of atoms, according to a 2001 study published in the journalNature. More recently, a 2018 study published in the journalPhysical Review Lettersproposed a new way to stop light in its tracks at "exceptional points," or pla...
Upon adding hydrogen atoms and counter ions (~150 mM NaCl) and solvating the structures in rectangular water boxes (>16 Å from the box edges and protein) by the VMD software package, we obtained two solvated systems—one for the hybrid and the other for WT H2-Kb—with dimension ...
Multiply the formula weight (or MW) by the desired molarity to determine how many grams of reagent to use: Chemical FW = 194.3 g/mole; to make 0.15 M solution use 194.3 g/mole * 0.15 moles/L = 29.145 g/L Example 2: To prepare a specific volume of a specific molar solution from a...
How many moles of CO2 are present in 220 mg? Convert 5.67 moles of NaOH to grams Find the molar mass of an NaOH. How many atoms make up this compound NaOH? How many moles of aluminum hydroxide are in 10 L of a 2.5 M solution of aluminum hydroxide? If you have 50.00 grams of sodi...

First, water molecules (two atoms of hydrogen and one atom of oxygen joined together) naturally stick to one another, so they clump together in big droplets on the window. The forces that make them do this are called cohesive forces (and the process involved is called cohesion). Second, ...
