How many moles are there in 140.g of potassium bromid

1 answer:

4 0

Molar mass KBr = 119.0 g/mol

1 mole ------- 119.0 g
? mole ------- 140 g

moles = 140 * 1 / 119.0

= 1.176 moles of KBr

hope this helps!

Using 273.15 K as the value for Zero degree Celsius convert 45.1° C to Kelvin. 6.05 K 318 K 318.3 K 1.23 x 104 K

OLEGan [10]

Zero degree celcius = 273.15 degree kelvin

Simply, to get the value of 45.1 degree celcius in kelvin, we will add 273.15 to the given value (45.1).

Degree in kelvin = 45.1 + 273.15 = 318.25 degree kelvin

Approximating to the nearest tenth, the value will be 318.3 degree kelvin

Methane burns in oxygen to produce carbon dioxide and water. Which of the tollowing represents a preliminary, unbalanced equatio

WITCHER [35]

So first we need to know what the formulas are:

Methane: $CH_{4}$

Oxygen: $O_{2}$

Carbon Dioxide: $CO_{2}$

Water: $H_{2}O$

So then we follow the equation as specified in the question. Note that it does not need to be balanced, as the question states it wants the unbalanced equation:

$CH_{4}+O_{2}$ → $CO_{2}+H_{2}O$

This is the preliminary, unbalanced equation with the correct chemical formulas.
