To find the number of atoms in 195 grams of calcium, you first need to calculate the number of moles of calcium using its molar mass. Calcium's molar mass is 40.08 g/mol, so there are 195g / 40.08 g/mol = 4.86 moles of calcium. Finally, one mole of calcium contains 6.022 x 10^23 atoms, so 4.86 moles x 6.022 x 10^23 atoms/mole = 2.95 x 10^24 atoms of calcium in 195 grams.

Micron to gram per meter square?
Converting between microns and grams per square meter is not straightforward as they measure different things - microns measure thickness while grams per square meter measure mass per unit area. To convert between the two, you would need to know the density of the material in question. Once you know the density, you can use the formula: grams per square meter = microns thickness * density.
Does bromine have a larger value for ionic radius than fluorine?
No, fluorine has a larger ionic radius than bromine. This is because fluorine, being in the second row of the periodic table, has fewer electron shells than bromine, which is in the fourth row. As you move down a group in the periodic table, the atomic size tends to increase.
Can the Mars night temperature drop to -200 degrees?
No, the lowest temperature recorded on Mars is around -125 degrees Celsius (-195 degrees Fahrenheit). While it can get very cold on Mars, it does not reach temperatures as low as -200 degrees Celsius.
What are the unique conditions on mars?
Some unique conditions on Mars include a thin atmosphere composed mostly of carbon dioxide, surface temperatures that can vary widely from -195°F to 70°F, and a lack of liquid water on the surface. The planet's dusty surface is also affected by intense dust storms that can cover the entire planet for weeks at a time.

Compare a mole of Ag-108 and a mole of Pt-195 using atoms protons electrons and neutrons?
A mole of Ag-108 contains 6.022 x 10^23 atoms of silver-108, which has 47 protons, 61 electrons, and 61 neutrons. On the other hand, a mole of Pt-195 consists of 6.022 x 10^23 atoms of platinum-195, which has 78 protons, 117 electrons, and 117 neutrons. Pt-195 has more protons, electrons, and neutrons compared to Ag-108.
