If the atomic mass of 1 oxygen atom is 15.9994 amu, how much mass does of 1 mole oxygen have?​

Chemistry
1 answer:
IrinaK [193]3 years ago
6 0

Answer:

15.9994 amu

Explanation:

By definition 1 mole of any substance is the mass that contains 1 Avogadro's Number of particle. (=> 6.02 x 10²³ particles/mole).

1 mole Oxy => 15.9994 amu => contains 6.02 x 10²³ particles Oxy /mole

1 mole Sulfur => 32.064 amu => contains 6.02 x 10²³ particles Sulfur /mole

1 mole H₂O => 18 amu => contains 6.02 x 10²³ molecules of water / mole.

How many orbitals does the P sub shell contain
IgorLugansk [536]

Answer:

Contains 3 orbitals. Px, Py, Pz.

Explanation:

Orbitals are regions in space where there is a high probability of finding electron(s). Each p orbital can hold 2 electrons, which means 6 in total. Hence the p block of elements is six across. Orbitals are more specific in giving the exact location of electrons and scientists use these electronic configurations to identify and distinguish different elements.

How much work is done by a 35-watt light bulb if it is on for 1,320 seconds?
OleMash [197]

Answer:

The 35-watt light bulb does a work of 46200 joules in 1320 seconds.

Explanation:

From Physics we remember the definition of work (W), measured in joules, by the following integral equation:

W = \int\limits_{0}^{t} {\dot W} \, dt (1)

Where \dot W is the power, measured in watts.

If the power is stable in time, then the work can be calculated by the following algebraic equation:

W = \dot{W}\cdot \Delta t (2)

If we know that \dot W = 35\,W and \Delta t = 1320\,s, then the work done by the 35-light bulb is:

W = (35\,W)\cdot (1320\,s)

W = 46200\,J

The 35-watt light bulb does a work of 46200 joules in 1320 seconds.
