How to convert miles per hour to centimeters per second [mi/h to cm/sec]:
vcm/sec = 44.704 × vmi/h
How many centimeters per second in a mile per hour:
If vmi/h = 1 then
vcm/sec = 44.704 × 1 = 44.704 cm/sec
How many centimeters per second in 50 miles per hour:
If vmi/h = 50 then
vcm/sec = 44.704 × 50 = 2 235.2 cm/sec
does this help?
Answer:
2.35 M
Explanation:
Molarity is mol/L of solution. We have to convert the g to mol and the mL to L. G to mol uses the molar mass of the compound. The molar mass of NaNO₃ is 85.00g/mol.
![50.0gNaNO3*\frac{1molNaNO3}{85.00gNaNO3} = 0.588molNaNO3](https://tex.z-dn.net/?f=50.0gNaNO3%2A%5Cfrac%7B1molNaNO3%7D%7B85.00gNaNO3%7D%20%3D%200.588molNaNO3)
Then you have to convert mL to L.
![250mL*\frac{1L}{1000mL} = 0.250L](https://tex.z-dn.net/?f=250mL%2A%5Cfrac%7B1L%7D%7B1000mL%7D%20%3D%200.250L)
Now divide the mol by the L.
![\frac{0.588mol NaNO3}{0.250L} = 2.352 M](https://tex.z-dn.net/?f=%5Cfrac%7B0.588mol%20NaNO3%7D%7B0.250L%7D%20%3D%202.352%20M)
Round to the smallest number of significant figures = 2.35M
Anions are basically atoms that carry a negative charge. A negative charge indicates that the atom has gained electrons . Atoms that gain electrons are nonmetals in group 6,7,8 since they lack a full stable outer shell so when they gain electrons they will form anions which as i mentioned previously are atoms with a negative charge.
