The answer is <span>A.0.5 moles
</span><span>a mole of sodium chloride weighs approximately 58 grams: 1 M - 58 g
</span><span>you have 29 grams of sodium chloride, how many moles of sodium chloride do you have: xM - 29g
1 M : 58g = x : 29 g
x = 1 M : 58g * 29 g = 0.5 M</span>
Answer:
150 m²
Step-by-step explanation:
area of triangle is 1/2(6)(9.5) = 28.5
there are 4 triangles
28.5 x 4 = 114
bottom is 6 x 6 = 36
114 + 36 = 150 m²
4x = 6x -10
2x = 10
x = 5
answer
x = 5
