To transform the amount in moles to systems of grams, we require the atomic mass that nickel which is 58.69 g/mol. Us multiply the number of moles to the atomic mass i m sorry cancels mole leaving us with units the grams.2.63 moles ( 58.69 g/mol ) = 154.35 g NickelHope this hunterriverpei.coms the question. Have a quite day.


You are watching: What mass (in mg) does 2.63 moles of nickel have?


The average trip speed that a bald eagle is around 50 Km/h. A scientist has actually measured and also equal paris 80 Km/h. Exactly how is this possib

What would the rate of each particle be if it had the exact same wavelength as a photon the violet irradiate ( λ = 400.0 nm ) ?

To construct this problem we will use the DeBroglie partnership for which the wavelength is considered as

*

Where,

h = Planck"s constant

m = mass

v = Velocity

*
= Wavelength

Rearranging the equation we have actually that the rate would be

*

Our offered values room considered

*

*

*

The value of the mass varies, therefore its rate would be offered as:

Proton

*

*

*

Neutron

*

*

*

Electron

*

*

*

Alpha particle

Hypotheses and theories concerned each other since hypotheses are supplied in developing a theory. Hypotheses are explanations for some phenomenon that are still proposed. As soon as these room validated and also proved, castle are welcomed by the public as theories and are used to describe natural phenomenon.
