(sorry if it's wrong)
Answer:
0.188mol
Explanation:
Using the formula as follows:
mole = mass/molar mass
Molar mass of hypomanganous acid, H3MnO4 = 1(3) + 55 + 16(4)
= 3 + 55 + 64
= 122g/mol
Mass of H3MnO4 is given as 22.912 g
Hence;
moles = 22.912 ÷ 122
number of moles = 0.188mol
In group theory, a branch of mathematics, the term order is used in two unrelated senses:
<span><span>The order of a group is its cardinality, i.e., the number of elements in its set. Also, the order, sometimes period, of an element a of a group is the smallest positive integer m such that <span>am = e</span> (where e denotes the identity element of the group, and am denotes the product of m copies of a). If no such m exists, a is said to have infinite order.</span><span>The ordering relation of a partially or totally ordered group.</span></span>
This article is about the first sense of order.
The order of a group G is denoted by ord(G) or | G | and the order of an element a is denoted by ord(a) or | a |.
