Flame photometer is used in the determination of
A flame photometer is commonly used to measure the concentration of certain elements, notably potassium and sodium, in soil and plant materials.
[123 ÷ 8 ÷ 9] × 144 = ? + 12 × 5
(11/12) × (18/22) × (4/3) + 3 = ?2
800 + 900 X (3)-2 - ? = 25 X 60 ÷ 2
25% of 30% of 3/5 of 14500 =?
(26)2 = {(20% of 40% of 18200) ÷ ?} × 1664 ÷ 128
15% of 360 × 20% of ? = 324
(8 x 9) ÷ 5 + ?2 = 23.4
(512) (2/3) × √64 ÷ (512) (1/3) = (64) (?/2) ÷ (2)6
(42% of 1500 + 170) ÷ 4 = ?2 - 52
25% of 60 × 15% of 120 = 30% of (?)
